Benefits of technology
The present technology provides a way to make rubber coated cords that can be replaced faster and more efficiently in continuous production. This is done by bonding the leading edge of one cord to the trailing edge of another, allowing for a seamless connection and continuous manufacturing process. This improves productivity and helps to speed up replacement work.
Problems solved by technology
The replacement work is cumbersome work involving, for example, disassembling a head part, causing a leading edge portion of the next cord to pass through the head, and re-assembling the head part, and thus requires a significant amount of time.

Embodiment Construction
[0033]A method and a device for manufacturing a rubber coated cord according to embodiments of the present technology will be described specifically below based on embodiments illustrated in the diagrams.
[0034]In a device 1 for manufacturing a rubber coated cord (hereinafter referred to as a manufacturing device 1) according to an embodiment of the present technology illustrated in FIGS. 1 to 3, an outer circumferential surface of a cord 18 (18a and 18b) is coated with unvulcanized rubber R extruded from a rubber extruder 2 and thus a rubber coated cord 19 (19a and 19b) is continuously manufactured. In FIGS. 1 to 3, the rubber coated cord 19a is manufactured by using the preceding cord 18a. The cord 18 is a metal cord or a resin cord, and for example, a twisted cord formed by twisting a plurality of filaments is used.
[0035]The manufacturing device 1 includes a pay-out unit 13 and a draw-out unit 14 for the cord 18, the rubber extruder 2 disposed between the pay-out unit 13 and the d...

Abstract
A method and a device for manufacturing a rubber coated cord, comprising:a rubber coated cord including a preceding cord is manufactured by causing the preceding cord to pass through a preceding head while filling the preceding head with unvulcanized rubber extruded from a rubber extruder, and a rubber coated cord including a next cord is manufactured by setting a leading edge portion of the next cord in a state where the leading edge portion of the next cord has passed through the next head in advance, manufacturing a predetermined length of the rubber coated cord including the preceding cord, and subsequently causing the next cord including a leading edge portion side range bonded to a trailing edge portion of the rubber coated cord including the preceding cord to pass through the next head while switching from the preceding head to the next head.
Description
TECHNICAL FIELD[0001]The present technology relates to a method and a device for manufacturing a rubber coated cord, and particularly relates to a method and a device for manufacturing a rubber coated cord that can provide accelerated cord replacement work and improved productivity in continuous manufacture of a rubber coated cord including an outer circumferential surface coated with unvulcanized rubber.BACKGROUND ART[0002]At the steps of manufacturing a rubber product such as a tire, a rubber coated cord including an outer circumferential surface coated with unvulcanized rubber is used. For manufacture of a rubber coated cord, an outer circumferential surface of a cord is coated with unvulcanized rubber by extruding the unvulcanized rubber into a coating head installed in a rubber extruder and causing the cord to pass through the coating head (for example, see Japan Unexamined Patent Publication No. 2008-272966). In the continuous manufacture of a rubber coated cord in this manner...
